METAL-TRANSFERRING APPARATUS.

$IECIFIOATION forming part of Letters Patent No. 745,252, dated November24, 1903. Applicationfi ed September 11. 1903- Serial No. l'72,802. (Nomodel.)

Figure 1 is a plan view showing a portion of a a rolling-mill plantprovided with my improved transfer system. Fig. 2 is a front elevationof the transfer-carriage, showing its' relation to the charging-machine,on an en- Fig. 3 is an end elevation of the transfer-car, showing aportion of the charging-machine; and Fig. 4: is a sectional detail viewshowing the dog and latch mechanism on the transfer-car.

My invention relates to the transferring of objects-such as metalingots, blooms, &c. and more particularly to transferring the metal froma heating-furnace to the feed-table leading to a rolling-mill,and it isdesigned to provide a simple and effective transfer mechanism wherebymetal may be brought from one or more furnaces out of linewith the tableinto a position at the end of the table.

In the'drawings, 2 represents a rolling-mill, and 3 a feed-table leadingthereto. I have shown the outer portion 3.of the feed-table as havingrollers shorter than those on the forward portion, though thearrangement of the rollers or other feed mechanism may be varied.

4 represents heating-furnaces, of which there may be any desired number,these having exit or draw-out'openings 5 on the side next to the mill.In front of this line of furnaces extend three parallel rails 6, 7, and8, on which are supported traveling chargingmachines 9. Thesecliargingmiachines may be of anyusual type and are employed in drawingthe blooms or heated pieces of metal from the furnaces. For this purposethe machine may have tongs movable longitudinally upon a beam 10 andactuated by a hydraulic cylinder 11.

The forward portion of the charging-machine is provided withlaterally-projecting brackets or supporting-fingers 12. The uppersupporting-surface of these fingers is preferably inclined outwardly anddownwardly, as

shown in Fig. 2, and the fingers are spaced at suitable distance apartto receive the metal ingot or piece 13 and allow the upwardly-projectingportions of the transfer-carriage to pass between them.Thecharging-machine is supported upon suitable wheels 14, travel ingupon its track.

Between the rails 6 and 7 of the chargingmachine track are located rails15, parallel therewith and forming atrack for the transfercar 16.'lhistransfer-car consists of a low framework mounted upon wheels 17below the level of the fingers 12 and having mounted in brackets orsupports thereon a set of rollers 18. The axes of these rollers,of which1 have shown three, are parallel with the track and with the axes of therollers on the rolling-mill feedtable. The plane of the upper surface ofthe rollers preferably intersects the inclined plane of the upper facesof the fingers 12, and the rollers are staggered relatively to thesefingers.

The transfer-car is provided between the rollers 18 with two pairs ofpivoted dogs 19, the

dogs of each pair being oppositely pivoted to the frame, as shown inFig. 4. The dogs are provided with depending tailpieces 20,having fiatinner faces 21 arranged to be en gaged by the ends of tilting latches22, pivoted to the carriage-frame between the pairs. Each latch 22 ispreferably enlarged at its center above the pivot, so that the weightwill hold it in either inclined position to which it is tilted. Thedownward movement of the latch is limited by the frame of the carriage,as shownin Fig. 4.

The transfer-table may be moved along its track by any suitable means,and I have shown for this purpose wire ropes 23 connected to oppositeends of the table and leading over suitable winding-drums,.by whichtheoperator may move the car to any desired amount in either direction.

In using the apparatus a heated bloom or piece of metal is drawn out anddeposited upon the fingers of one of the charging-machines, as showninFig. 3. The operator then moves the transfer-carriage toward thischarging-machin e, and as the rollers and dogs pass between the fingers12 the nearest dogs of each pair will tilt freely as they contact withthe metal to be rolled. The transfer-carriage latches 22.

is stopped when the front dogs of each pair pass beyond the metal, andthese tilted dogs then swing back to their normal vertical positionunder the action of gravity on their tailpieces. The carriage is nowdrawn back in .the direction from which it came, and the from thecarriage-rollers onto the rollers of the feed-table by a suitable motivecylinder, (indicated at 24.) It will be noted that as the dogs contactwith the metal and tilt in passing under it they force the latches intoinclined positi0n,where they will stop thebackward tilting of the dogs011 the return movement. The carriage may therefore be used in themanner above described in connection with the charging-machine on eitherside.

An important feature of the invention lies in the fact that thetransfer-carriage if accidentally moved beyond the desired point willnot be injured nor cause injury to the chargin g-machine. Thus if thecarriage moves too far the other set of dogs will tilt idly backwardlyand allow the carriage to pass on. In this case the operator will thendraw the carriage back to bring both sets of dogs on the other side ofthe metal and then repeat the forward movement and stop this movementwhen the dogs are on each side of the metal, and in repeating theforward movement the forward set of dogs will always set the latch toprevent backward movement of the dogs when the carriage is stopped atthe proper point.

The advantages of my invention result from the simple and efficientarrangement of the transfer-carriage. The dog system does away with thenecessity for raising or lowering the transfer-carriage, prevents anyaccident by moving the carriage too far, and will work equally well ineither direction of travel. By using the supports or fingers from whichthe car transfers the metal the car does not wait for the bloom to bedrawn out. The capacity is therefore greatly increased, since the metalis drawn out and thereafter transferred by the car.

The fingers or supports may be made in the form of long rails orsupporting-bars extending along the furnace and in front of thefeedtable. In this case the dogs on the carriage would simply move thebloom along the rails without transferring the metal to the-car. Itherefore use the words transfer-carriage in my broader claims asmeaning a support for the dogs, but not necessarily receiving the metalupon it.

The apparatus may be used in transferring any metal or material from onepoint to another, and the dog system maybe varied without departing frommy invention.

I claim 1. The combination with a support having separated members, of atraveling carriage having dogs arranged to transfer the metal from themembers to the carriage; substantially as described.

2. A transfer-carriage having oppositelylocated tilting dogs, and meansfor preventing back swinging of either set of dogs; substantially asdescribed.

3. A transfer-carriage having oppositelylocated dogs and a tilting latchbetween said dogs; substantially as described.

4:. A transfer-carriage having a pair of oppositely-located tilting dogsprovided with tailpieces, and a tilting latch between the dogs andarranged to contact with their tailpieces substantially as described.

5. A transfer-carriage having a pair of oppositely-located tilting dogsprovided with tailpieces, and a tilting latch between the dogs andarranged to be tilted by the dogs; substantially as described.

6. The combination with a charging-mm chine having separated fingers, ofa transfercarriage having dog mechanism arranged to pass between thefingers and transfer the metal therefrom to the carriage; substantiallyas described.

7. The combination with a pair of chargingmachines havingsupporting-fingers projecting toward each other, of a transfer-carriagebetween the machines and having dog mechanism arranged to transfer themetal from either set of fingers to the carriage; substantially asdescribed.

8. A transfer-carriage having oppositelylocated tilting dogs, both ofsaid dogs being arranged to tilt as they pass under the bloom or metal,and mechanism for preventing the tilting of one of the dogs in the otherdirection when the carriage is stopped at the proper point;substantially as described.

9. A transfer-carriage having oppositelyarranged pivoted dogs, and alatch pivoted between the dogs, said latch being arranged to be tiltedby the dogs and to alternately engage the tailpieces; substantially asdescribed.

10. The combination with a furnace of a support in front of the furnacehaving separated members or fingers and a movable support or .carriagehaving mechanism thereon arranged to transfer the hot metal from a pointin front of the furnace to another point laterally removed therefromsubstantially as described.

In testimony whereof I have hereunto set my hand.
